Alexandre Lacazette has found a new home; Arsenal have a new hero. The boy from Lyon who, it was feared, would struggle away from France has lit up the Emirates Stadium since his arrival for a club record £52 million fee with four goals now in his first three Premier League matches here. The No 9 is leading the line. This was a night for records with Gareth Barry making his 633rd league appearance, more than any other player in the Premier League era, beating Ryan Giggs' total, but – more relevant to this result – Lacazette became the first Arsenal player to score in his first three home league games for the club in those 25 years. The first player to do so, in fact, since Brian Marwood - 29 years ago. West Brom will feel there is another record after this – the poorest refereeing performance they have endured for some considerable time as Bobby Madley denied them a clear first-half penalty, before Lacazette had opened the scoring, and then awarded a far more dubious spot-kick to Arsenal in the second-half. Albion manager Tony Pulis was canny enough not to be drawn on Madley’s performance but his anger was clear enough and not just from his furious and increasingly incredulous touchline reactions. Mustafi takes down Rodriguez Credit: DYLAN MARTINEZ/REUTERS What is more worrying for the sport, in general, is that when Jay Rodriguez was obviously fouled by Shkodran Mustafi as he ran into the Arsenal penalty area, after being picked out by Barry with a typically shrewd through-ball, the striker picked himself up and carried on. It will lead to a debate as to whether Rodriguez is simply then being too honest and should have exaggerated the incident. Rodriguez then curled a shot that appeared set to beat Petr Cech but the Arsenal goalkeeper reacted superbly to get his fingertips to it and push it onto his far post. Even then the rebound fell to the onrushing Jake Livermore who made a hash of it and bundled his shot wide. Did Madley play advantage? Maybe so. But there is nothing in the rules stopping him from still then awarding the penalty as he surely should have done. And so there was yet more controversy around the refereeing of a Premier League match. Pulis had already been infuriated when Alexis Sanchez had gone down easily – he dived, Pulis bluntly said – to win a free-kick which he fired narrowly wide, and then Arsenal won another. Again it appeared a dubious award as Jonny Evans was harshly adjudged to have fouled Mohamed Elneny. Once more Sanchez took it, forcing a fine flying save from Albion goalkeeper Ben Foster with the ball rebounding off the cross-bar and Lacazette reacting quickest to head it into the net. Arsenal vs West Brom shots on goal It was the first time Lacazette and Sanchez had started together for Arsenal and it already looked like a potent combination. Interestingly, Mesut Ozil, fit again after his knee problem, was consigned to the bench, coming on as a late substitute, and it will be instructive if he is now included in the squad for the Europa League trip to Belarus to play BATE Borisov. Arsene Wenger is promising to take an experienced team and a group of young substitutes with a home league match next Sunday lunchtime against Brighton. He complained of a “cruel” schedule already for his side. “It was nervy,” Wenger later said of this encounter, and it was. The goal did not settle Arsenal who knew they had to win to lift themselves closer to the top of the table. A draw, even, was not enough and these points take them up to seventh, just behind fourth-placed Tottenham Hotspur but six behind the Manchester clubs at the top of the table. Already they are playing catch up. Monreal clears the ball off the line Credit: Michael Steele/Getty Images They should have been caught out here, though, when Grzegorz Krychowiak claimed the ball and ran on and on from his own half to then cross for Rodriguez who, unmarked, directed his header past the stranded Cech only for Nacho Monreal to, superbly, improvise and clear it off the line. On half-time it was Cech, down by his post, fending off Rodriguez and somehow Albion remained in arrears. Half-time appeared to stabilise Arsenal and Lacazette almost doubled his tally when Elneny worked his way into the area, holding off Barry, to slip a pass to the French internatinal whose low goal-bound shot spun up of Kieran Gibbs’ boot and just over the bar. After that a corner was won and met by Mustafi who cleverly back-heeled up towards the near post with Foster reacting alertly to clutch at the ball. Lacazette stoops to head in the opener Credit: IAN KINGTON/AFP Soon after and Arsenal had a penalty of their own as Aaron Ramsey turned and drove into the area only for Allan Nyom to step across and challenge. It appeared shoulder-to-shoulder, if a tad robust, and Ramsey went down with Madley pointing to the spot. Lacazette took the kick and although Foster guessed right, down to his left, the striker found the corner of the net. It was another calm execution from Lacazette. Would he complete a hat-trick? A chance came as he deftly brought down Sanchez’s cross only to slice his shot from a tight angle with Foster stranded. It did not matter. He had already won this game. “He gets stronger in every game,” Wenger later said of Lacazette. “Good first touch and movement. He is young and just arrived in England. The physical demands are very high." Lacazette, though, is answering them. 9:53PM Full time Arsenal secure a deserved victory with a commanding second-half performance after a shaky first-half. West Brom should have had a penalty at 0-0 but after half-time they were dominant with good performances from Alexandre Lacazette, Alexis Sanchez, Hector Bellerin, Sead Kolasinac and Nacho Monreal. Arsenal move up to seventh, West Brom drop to 12th 9:52PM Time on ball (at full time) Possession: Arsenal vs West Brom 9:52PM Average touch positions (full time) Average touch positions (full time) 9:50PM 90+3 min Maitland-Niles will now get on for 10 seconds, replacing Ramsey. Half the crowd seems to have gone home. Sell the seats to Koln fans. 9:49PM 90+1 min We'll have three bonus minutes. Maitland-Niles waits patiently to come on but he may be deprived by Arsenal's long spell of keepball. 9:48PM 90 min Arsenal break quickly and feed a pass through to Ramsey running into the box on the right. It's slightly behind him so he has to check his run and stabs a shot at Foster's feet. 9:47PM 89 min A few decent touches and a lovely pass from Barry in the first half as well as his customary good positioning but he's had no chance to shine since. 9:45PM 87 min Giroud is found with a chipped pass down the inside-left channel. He traps it on his chest but instead of turning to shoot because Dawson is so tight, he lays it back to Xhaka who wellies a shot on the run over the crossbar. 9:44PM It's been a mismatch at Emirates Stadium so far Arsenal are dominating this game, firing in a total of 15 shots compared to seven from West Brom so far. Arsenal vs West Brom shots on goal 9:43PM 86 min Elneny's back-post cross from the right is cleared by Dawson but in general their balk retention and game management has been excellent this half. 3 - A. Lacazette is the first Arsenal player to score in his first 3 home league apps for the club since Brian Marwood in Sept 1988. Gunner. pic.twitter.com/9Q8pwxwTEc— OptaJoe (@OptaJoe) September 25, 2017 9:42PM 84 min Arsenal, hounded by West Brom, go backwards from the corner until Rondon goes in too hard on Koscielny when attempting to close him down. 9:40PM 82 min Goroud replaces Lacazette, Ozil comes on for Sanchez. Both leave to hearty applause. 9:40PM 81 min Arsenal corner taken short to Bellerin. West Brom have atypically gone to sleep at a set-piece. Bellerin, 20 yards out, takes a stride and smashes a right-foot shot that is deflected over. Another corner but before that ... 9:38PM 79 min The crowd bays for Dawson's blood, or the very least a second yellow, when he brings down Sanchez from behind. Bobby Madley gives him a telling off instead. It's all Arsenal and has been all half. 9:37PM 76 min West Brom have the ball inside the Arsenal half and lift up a long ball for Rondon on the edge of the box. It was too steepling a pass for him to be able to meet it with any force. He knocked it up and Arsenal clear. Have had to make a correction, two entries ago: Nyom, not Rodriguez, departed. Virtual doppelgangers, how can anyone tell the difference? 9:36PM Time on ball (60 - 75 min) Possession: Arsenal vs West Brom 9:34PM 75 min Lacazette tucks away the penalty Credit: Mike Hewitt/Getty Images 9:32PM 73 min Matty Phillips comes on as West Brom's final sub. Nyom departs. Xhaka bludgeons a shot wide that was set up by Sanchez's exquisite trap with the sole of his boot and chipped pass to Ramsey who laid it off with a no-look insouciance. 9:30PM 70 min Ball from the left over the top finds Lacazette in the area. Shades of Bergkamp 98 in the gorgeously cushioned first touch, but the second touch and finish are dreadful, bloodless cover versions. Like something by Nouvelle Vague. 9:27PM 68 min Ramsey goes on a run into the box from the left along the byline. Nyom, in pursuit, attempts to go shoulder to shoulder with him and charge but fails his anatomy viva by connecting his shoulder with the middle of Ramsey's back, sending him flying in the process. There's a time and a place for a risj-free shoulder charge in the box in any case. 1959 to be exact. What was he thinking? 9:25PM GOAL! West Brom up against it now - Alexandre Lacazette makes it 2-0 to Arsenal. Arsenal 2 - 0 West Brom (Alexandre Lacazette, 67 min) 9:24PM Lacazette scores Squeezes it in the bottom right corner. 9:24PM Arsenal penalty Lacazette will take. 9:24PM 65 min Bellerin gets another cross in from the right that is blocked by Evans. Check out his touch map for how influential he has become as an attacking force. Average touch positions (66 min) 9:21PM 64 min Second West Brom sub: Rondon on, Hal Double-Banger off. 9:20PM 63 min West Brom sub: James Morrison, a veteran of that victory at the Emirates in 2010, replaces Livermore. 9:20PM Time on ball (45 - 60 min) Possession: Arsenal vs West Brom 9:19PM 62 min Arsenal attack up the right with Elneny and Bellerin interchanging passes until Elneny goes for the cross that Gibbs blocks. 9:18PM 60 min Kolasinac shoves Nyom over and West Brom have a free-kick just inside the Arsenal half. Up go the centre-backs, Krychowiak bends it with his right foot towards the 18 yard line but sends it too deep into the box, allowing Cech the time to reach it and punch clear. 9:16PM 58 min Krychowiak overhits a pass up the right intended for Nyom but Kolasinac gets there first because of the extra weight of the delivery. West Brom have been garbage so far this half. 9:14PM 55 min Arsenal free-kick on the left after Krychowiak brings down Elneny and goes into the book. Sanchez will take and whips it to the near post to meet Monreal's run but Dawson stands firm. 9:12PM 53 min Cute corner routine from Arsenal. It's spun to the neat post and Mustafi's run. He tries to backheel it in on the run but Foster was wise to it and pulls off a very smart save. 9:11PM 51 min Kolasinac goes bullocking down the left and squares the ball to Elneny in the box. he takes a clever touch then rolls it to Lacazette. The centre-forward shoots on target ... until Gibbs throws himself at it and makes a vital block that diverts the ball over the bar. 9:08PM 50 min Dawson, bamboozled by Sanchez's quick feet, counters with some brute force, illegally. Free-kick that comes to naught. 9:07PM 48 min Good pass from the centre circle from Xhaka to Sanchez who makes 10 yards and gives it him back and Arsenal enjoy a spell of possession camped 25 yards out until Lacazette beats Livermore and spins a pass around to Bellerin advancing to the touchline. He has one option, to whistle a low cross through the six-yard box which he does but Ramsey was too late making his back-post run and cannot get there so the ball is whisked away from danger. 9:04PM 46 min 'Does a terrific job, wherever he is,' says Alan Parry of Tony Pulis. Is that faint praise? Livermore dispossesses Xhaka and bombs on into the Arsenal half. He feeds Krychowiak who is robbed by the alert Monreal. 8:53PM Here's that Mustafi foul on Rodriguez Mustafi slides through Rodriguez Credit: DYLAN MARTINEZ/REUTERS 8:48PM Half time Arsenal look very vulnerable on the break, down the flanks particularly. Sanchez is playing very well as an attacking force and is linking promisingly with Lacazette. Elneny has had some bright touches but they are allowing West Brom too many chances for comfort so far. 8:46PM 45 min The free-kick hits a well-stationed Arsenal defender and is nodded out for the corner. The second phase ball from the corner whizzes through the six-yard box, Bellerin misses his intended clearance and Rodriguez, from the tightest angle when played in by Barry's cute header, can't turn it in beyond the far post. 8:46PM Time on ball (first half) Possession: Arsenal vs West Brom 8:46PM Average touch positions (half time) Average touch positions (half time) 8:45PM 44 min Arsenal are penalised for Kolasinac's challenge on the left. Sanchez protests, places his arm on Bobby Madley's chest to remonstrate and is booked. Sanchez continues to stew and continues 'on the argue', as one character puts it in Down and Out in Paris and London. Madley calls over his captain Koscielny to witness the final warning. 8:43PM 42 min Another chance for the Baggies from a throw on the left that begets a cross for Rodriguez. The centre-forward makes a glancing header at the near post but his connection is too slight so it goes horizontally through the six-yard area. Robson-Kanu is two shoe sizes away from turning it in. It's very quiet again and you can hear Pulis bellowing. 8:41PM 41 min The chance a minute ago was aided by Ramsey's wayward pass. Now Eleneny loses the ball cheaply and Rodriguez scuds a low shot wide. He hit it with his right and it kept going past the left post. 8:40PM 40 min West Brom should have scored and would have but for Monreal's tenacity. A hanging left-wing cross is met by Rodriguez who makes a complete moose of his connection. It still dribbles towards goal, past the committed Cech and Monreal sprints after it and hooks it off the line. 8:38PM 37 min Sanchez takes and gets it over the wall, aiming for the right post. It panics Foster who scrambles across goal in a fluster but it's a good yard wide. Arsenal vs West Brom shots on goal 8:36PM 35 min Lacazette's fast feet to move the ball away from Evans 25 yards out results in an Arsenal free-kick because Evans, in a tangle steps on top of Lacazette's foot. Snachez to take. It's pretty central and Foster is making himself hoarse lining up his wall. 8:34PM 34 min Sanchez appeals for a penalty from the corner because Krychowiak has a fistful of his shirt. Which he does but Bobby Madley, not for the first time, doesn't see it that way. 8:33PM 32 min Great pass from Sanchez, stroked with his right instep to the right of the six-yard box after more promising foraging graft from Eleneny in the D. Ramsey was perhaps a touch too wide but he spun on the ball quickly and fired a shot at Foster who saved sharply from five yards though the angle was in his favour. Corner. 8:33PM Time on ball (14 - 29 min) Possession: Arsenal vs West Brom 8:31PM 30 min Koscielny races out to the right of his defence to stop Rodriguez's advance. Tony Pulis must think Bellerin and Koscielny leave enough space for Rodriguez and Gibbs to exploit as both keep popping up behind the Arsenal wing-back. Robson-Kanu too has faded a few runs out there but it does leave only Krychowiak to bomb into the box if they do create something with numbers in that gap. 8:28PM 28 min Excellent close control from Monreal allows him to elude Nyom and Dawson as he glides into the box. Eventually he runs out of space to dig a shot out that would have gone over Foster but that may have been because Nyom was, by then, illegally impeding him. 8:27PM 26 min Elneny moved the ball quickly in the box to Kolasinac after some smart short passing from Lacazette and Sanchez. Kolasinac gave it him back but he had made a different run to the one the left-back anticipated. 8:25PM 24 min Here's Lacazette's finish: Lacazette makes it 1-0 to [the] Arsenal Credit: IAN KINGTON/AFP 8:24PM 22 min Tony Pulis, aggrieved by the lack of a penalty for his side, and possibly arguing its stonebonker quotient, is protesting the award of the free-kick for Evans' trip of Elneny as he tried to pick up Bellerin's prodded pass. He fell, writhing, acting like a bit of a blouse but there seemed to be contact. 8:21PM 21 min Sanchez chips the free-kick right into the meat of the crossbar via Foster's fingertip. Lacazette, in like Flynn to beat Hegazi and co, has a simple nod-in to score another goal at home. 8:20PM GOAL! Alexandre Lacazette scores for Arsenal to make it 1-0! Arsenal 1 - 0 West Brom (Alexandre Lacazette, 20 min) 8:19PM Goal!! Lacazette gives Arsenal the lead. 8:19PM 18 min Elneny, who is having a good game, is blocked by Evans just to the right of the D. Free-kick that Sanchez tees up. 8:18PM 16 min Lacazette runs the inside-right channel but isn't played in. Back come West Brom. Ramsey looks uncomfortable in this role on the right but not half as out of sorts as Koscielny who flays a simple clearance into touch. 8:17PM Time on ball (0 - 15 min) Possession: Arsenal vs West Brom 8:15PM 14 min Robson-Kanu gives Bellerin a chasing down the Albion left. Mustafi helps him out but the ball breaks to Gibbs who smashes a left-foot shot over the bar, as if all his Christmases had come at once. He gave it the kitchen sink (and twin-tub washing machine) 8:14PM 11 min Arsenal set up a chance at the near post with Elneny's hanging crossfield pass. Bellerin stands it up and Ramsey heads over. It's all gone ridiculously quiet at the Emirates, perhaps because Arsenal look rattled at the back and should have been penalised with a penalty. 8:12PM West Brom have their first sight of goal West Brom respond to the earlier Arsenal effort with their first shot of the game. Arsenal vs West Brom shots on goal 8:12PM 9 min West Brom are denied a cast iron penalty when a mistake by Bellerin lets Rodriguez chase a hare down the left. He sprints after the through-ball from Barry into the box, Mustafi slides in and catches him with his foot, felling him at the ankles. No whistle so Rodriguez leaps up and shoots. Cech tips it on to the post and they squeeze our Livermore's attempt to latch on to the rebound. As Monreal and Kolasinac dived in Livermore skewed his effort round the post. Did the referee play the advantage? He shouldn't have. Take On: Arsenal 0 - 0 West Brom (Jay Rodriguez, 8 min) 8:11PM Arsenal enjoying plenty of touches of the ball so far. Arsenal have had 121 touches of the ball compared to 31 by West Brom. Arsenal vs West Brom 8:07PM 7 min Arsenal build from the back by switching via Cech from right to left but they make little headway into the West Brom half until they move it back to the right and Gibbs' gets his toe in to concede a throw-in. Pulis screams across at Nyom to adjust his position and from 10 yards inside the Baggies' box Arsenal go back to Cech. 8:05PM 5 min Sanchez is tripped 19 yards out by the angle of the box on the left. Sanchez takes it himself and tries to bend a shot round the wall and in at the far post but it keeps to the virtuous path and doesn't curl enough to trouble a static Foster. 8:03PM 3 min The corner doesn't beat the West Brom Sequoias. The ball falls to Bellerin at the edge of the box. The crowd urges him to shoot, but Ray Parlour he ain't so he lays it off. 8:02PM 2 min Robson-Kanu and Rodriguez, as you'd expect, are running their socks off to press Arsenal at the back but they break free and Sanchez earns a corner with a shimmy. 8:01PM 1 min Arsenal kick off and move the ball from right to left. Bellerin plays the percentages to win a throw-in off Gibbs - 'welcome home Kieran' - and hurls it back to Cech. 7:58PM Here come the teams Arsenal double high five each other, slapping both palms above their heads, instigate, I think, by Monsieur Lacazette. 7:49PM Tony Pulis and Arsene Wenger speak Says the Albion's formation is more of a swivel-four at the back when they've got the ball. Presumably meaning that when Gibbs slips into midfield, Evans takes over at left-back, and Dawson does the same for Nyom when he goes forward. Interesting. Wenger was asked about Sanchez's form and fitness earning him a recall into the starting XI. He agrees that Sanchez showed 'against Doncaster' that he was approaching his best levels again but he emphasises he is not guaranteed a place even if he is in peak form. 'That depends, as always, on the team.' I suppose that means he is trying to stress that he devotes more to analysis of the opposition and makes more appropriate changes than his critics contend. 7:40PM Here's the man of the moment Gareth Barry makes his 633rd Premier League appearance, admirable indeed but still 216 short of Peter Shilton's English top division record. Credit: Reuters/Andrew Couldridge "It’s a nice moment for myself," he says. "I’m very proud. But I’m going to put it to the back of my mind, and just try to win the game. I can think about it afterwards." 7:17PM Those teams in the orthodox style Arsenal Cech; Mustafi, Koscielny, Monreal; Bellerin, Xhaka, Elneny, Kolasinac; Ramsey, Sanchez; Lacazette.

I’ve got a great record against them at home for whichever clubs I’ve managed in the Premier League – but I must admit the record at their stadium is the opposite. It would be nice to change that.”West Brom manager Tony Pulis What does the table look like? What are the odds? Arsenal to win: 4/11 Draw: 4/1 West Bromwich Albion to win: 8/1 Best-priced accumulators | New customer offers What's our prediction? Apart from the impressive goalless draw away to Chelsea last Sunday Arsenal have failed to convince this season while West Brom are West Brom – hard to beat, albeit apart from their last away game against Brighton. Arsenal must not concede set-pieces or they will be in trouble. Another tight game can be expected and frustration for Arsenal. Jason Burt's prediction: 1-1
